scrie sub forma de fractie numerele 0,16 -3,14 0,(8) -5,(7) 0,3 (5) 8,21(6) -4,97(35).

Answer 1

[tex]0,16 = \frac{16}{100} = \frac{4}{25} \\ \\ -3,14 = \frac{-314}{100} = \frac{-157}{50} \\ \\ 0,(8) = \frac{8}{9} \\ \\ -5,(7) = (-5)*\frac{7}{9} = \frac{-52}{9} \\ \\ 0,3 (5) = \frac{35-3}{90} = \frac{32}{90} = \frac{16}{45} \\ \\ 8,21(6) =8 \frac{216-21}{900} = 8\frac{195}{900} = 8\frac{39}{180} = 8\frac{13}{60} = \frac{8*60+13}{60}= \frac{493}{60} \\ \\ -4,97(35) = -4\frac{9735-97}{9900} = -\frac{4*9900+9638}{9900} = -\frac{49238}{9900} [/tex]
